Hi CatDoc. I did take my dog to the vet today and he confirmed that my dog probably has degenerative myleopathy. Clinical diagnosis is based on ruling out other diseaseas. He did try her on Rimadyl 75 mg bid for a week. If it was any type of arthritis she would have improved. The vet checked her reflexes and they are hyper, more reactive. Her hips seem to be okay and along the spine area too. Could this still be hip dysplasia? Would x-rays help? He did mention about doing x-rays. I have read that a defininitive diagnosis of degenerative myelopathy is only ever determined postmortem.
